Cortical Thickness values
by Natasha Haris 11 Feb '14

11 Feb '14

Dear Freesurfers, Is there anyway to get a compiled list of all the significant clusters with information about their maximum thickness value, x/y/z vertices, t statistic etc on QDEC? Does this have anything to do with a SaveClusterFile command? All of this information must be stored somewhere for the significant clusters to appear - wondering what's the easiest way to extract this info. Thanks, Natasha

Dear guys, Is there some way to have a more detailed look of the recent changes on the FreeSurfer Wiki page? I click on the recent changes option but can only see the latest 13 updates within around 10 days. Could I have a check of that from further past days? Thanks a lot, Kaiming

woops- sorry meant to include everyone. The name of the file I use to plot is "lh.pial-outer-smoothed." So I either want to create this file or figure out another way to plot. Do i need lh.pial to make lh.pial-outer-smoothed? ________________________________________ From: Bruce Fischl [fischl(a)nmr.mgh.harvard.edu] Sent: Tuesday, February 11, 2014 10:51 AM To: Borzello, Mia Subject: Re: [Freesurfer] creating specific files Hi Mia can you keep ccing the list?

creating specific files
by Borzello, Mia 11 Feb '14

11 Feb '14

Hi Freesurfers, I was wondering if there was a way to kind of fill in the blanks for a Surfer Output folder. I am working with an old data set, and it seem that some of the files are empty (0 bytes), "rh.pial" for example. Is there a way to pass the SurferOutput folder in and recreate what's missing? Thanks, Mia

How to caulculate the differences in subcortical volumes and display it?
by Wang, Guoying 11 Feb '14

11 Feb '14

Dear freesurfer experts, I am trying to compute the differences in subcortical volumes between two groups. I have read previous mail, https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg17597.html , and in this mail, your answer was 'you can do a subcortical volume analysis by working with the aseg.stats file directly or compute with mri_glmfit'. So, I tried to use 'mri_glmfit' to calculate it . but without specifying the argument '-surf' (because it is mentioned in your webpage that 'if -surf is not specified, then mri_glmfit will assume that the data are volume-based and use the geometry as specified in the header to make spatial calculations'). However, when I ran the command, it gave me the error message which said :' you must use-surface subject hemi' with surface data'. Do I misunderstanding some point? On the other hand, if there is statistical differences in subcortical volumes. How to display them in freesurfer? Sorry, I am a beginner. I know someone asked this question before, but I am still not fully understand it . Thank you for your help and reply in advance !

wmparc
by sujith vijayan 11 Feb '14

Hi All, I have a few questions about wmparc: What rule is used to determine what grey matter structure corresponds to a white matter point? What exactly has to be the case when UnsegmentedWhiteMatter is reported? Is there a reference you could point me to? Thanks, Sujith

combining FS commands
by Erik Lindberg 11 Feb '14

Dear Freesurfers, I want to run: mri_normalize gentle, And mris_make_surfaces min_border_white 85 -min_gray_at_white_border 80 in MY recon-all script. I understand that I have to put the flag -expert to do this - but I seem to make errors in my command It would be greatly appreciated if you can tell me how the command should be written Thanks in advance!

Dear Freesufers, I want to run: mri_normalize gentle, And mris_make_surfaces min_border_white 85 -min_gray_at_white_border 80 In as few steps as possible as I will run around 800 images. So far I only managed to this by braking up the process several subparts (like doing autorecon1 before mri_normalize, and autorecon2 before mris_make_sufaces If this could be combined somehow it would of course be a lot easier than running step by step 800 times. Thanks in advance Erik

Re: [Freesurfer] Choi's parcellation expansion inquiry
by Thomas Yeo 11 Feb '14

11 Feb '14

Hi Sooyun, It is possible that tri-linear might work better, but I have to caution that you will get non-integer values. Have you tried mri_label2vol? According to Doug in the last email, mri_label2vol might work better than mri_vol2vol. My suggestion is to first verify whether the transformation from Choi parcellation to the subject's native space is good enough. To do that, instead of transforming the Choi parcellation, try transforming the MNI152 template accompanying the Choi's parcellation (NOT the FSL MNI152 template). If the transformed MNI152 template does not match your subject's native anatomy to your liking, then you need to improve the transformations. Again, can you clarify where you are obtaining the transformation matrices? Recall that I previously told you that to convert the Choi's parcellation to the MNI152 template from FSL, you should just use mri_vol2vol, rather than FIRST. The command is as follows: "mri_vol2vol --mov original_choi_MNI152_parcellation.nii.gz --targ $FSLDIR/data/standard/MNI152_T1_2mm_brain.nii.gz --regheader --o FSL_choi_MNI152_parcellation.nii.gz --no-save-reg --interp nearest". And the reason is that the Choi volume is in exactly the SAME space as the $FSLDIR/data/standard/MNI152_T1_2mm_brain.nii.gz, it's just that the header information is different. Therefore the "regheader" flag takes care of that.
